如何不使用await改写fetch调用代码？解决eval中await失效问题

Hey there! Let's sort out this fetch/await issue you're hitting in AutoHotkey.

The problem with using await directly inside eval() is that eval runs in a non-async context—await only works inside an async function, which is why it wasn't taking effect. Since you mentioned you'll be checking window.items_list periodically anyway, we can rewrite the code to use plain Promise chaining instead of await, which works perfectly without needing an async wrapper.

Here's the revised code:

fetch(ff_url, ff_params)
  .then(response => response.json())
  .then(data => window.items_list = data.items);

This does exactly the same thing as your original code: it sends the request via fetch, parses the response as JSON, then assigns the items property from the response to window.items_list. The only difference is we're using fetch's built-in Promise chain instead of await, so it'll run correctly when injected via eval() in your AutoHotkey setup.

Since you're already planning to check for window.items_list being defined later, this fits your workflow perfectly—once the fetch completes and the JSON is parsed, the variable will be set, and your periodic check will pick it up.
